The Straight Up Guide to Essential Oil Research

Whenever I talk about essential oils, it occurs to me that we have it all backwards. Why is it that the natural leaves and herbs, the stuff that nature intended to cure us, is considered “alternative,” while products that are developed in a lab and laden with chemicals are considered “mainstream?”

With that, it makes sense that some people are just skeptical about natural alternatives such as essential oils. It’s okay. I get it. Living in the pharmaceutical belt of the country, we probably have a lot of naysayers around here. What I wanted to do is collect the data behind the oils, the science – the research. As a former researcher myself, I understand the need for validation. You want proof from a third party. You want the essential oil research. So here it is, folks.

Before I begin, please note that I am not a doctor, nor do I play one on this site. Though there is plenty of essential oil research, essential oils are not regulated by the FDA. (Again, this seems somewhat backwards thinking, does it not?) Because they are not evaluated by the FDA, they are not formally regulated to treat, diagnose, cure or prevent any illness. With that said, here are some of the results of scientific studies on essential oils by ailment:

The Straight Up Guide to Essential Oil Research

Allergies
Seasonal allergies stink, particularly for people who have them during every season of the year.Both Lemon essential oil and Lavender essential oil have proven antioxidant properties that can help fight off seasonal allergies and allergic rhinitis. Meanwhile, Sage also has disinfectant properties and can manage airborne microbes when diffused.

Alopecia
A study of essential oil aromatherapy shows benefits in the treatment of Alopecia.

Alzheimer’s Disease
Essential oil aromatherapy research shows strong potential for improving cognitive function in Alzheimer’s patients.

Bacteria/Fungus
Many studies have been done to verify the benefits of essential oils for their powerful antibacterial and antifungal properties. Peppermint and Spearmint essential oil can be used as potential antibacterial agents for inhibition of the growth of pathogens. In one particular study, the oils derived from spices and herbs, such as Thyme, Mint, Cinnamon, and Clove were found to have some of the strongest antimicrobial properties. Oregano also has powerful antimicrobial effects. In fact, research shows that is as effective as detergent solution for hand washing and cleaning surfaces.

Blood/Circulation
Lavender has been shown to improve the blood’s circulation in the body. Applying Black Pepper to veins prior to needle insertion can help to make veins protrude for easier needle insertion.

Cancer
Essential oils are being studied often for their potential benefits to cancer patients. After essential oils were inhaled, markers of the fragrance compounds were found in the bloodstream, suggesting that essential oil aromatherapy affects the body directly as well as indirectly through the central nervous system. To that end, Chamomile oil has shown significant effects on inhibiting cancer cell growth and mast cell degranulation, while Eucalyptus oil can boost immune system response which may protect the body after chemotherapy. Some patients have insomnia or restless nights after treatment, and Valerian essential oil has been shown in studies to help with a more restful night’s sleep.

As far as research towards specific cancers, Frankincense and Sandalwood together have shown to be effective in the treatment of bladder cancer. Blue Yarow may be effective for the treatment of skin cancer melanoma. Patchouli has shown to decrease cell growth in colorectal cancer cells, while Geranium has shown to aid in the reduction of colon cancer tumor growth.

Cognitive Function
In terms of cognitive function, Peppermint can enhance one’s memory as well as increase alertness. While it can lower stress levels, Lavender is also effective for increasing attention span. Rosemary essential oil has been shown to enhance cognitive function, with significantly improved performance on concentration exercises. Sage oil has been shown to improve memory and attention.

Some school teachers diffuse a combination of these oils in the classroom (along with antimicrobial oils for killing germs).

Lemongrass oil can help treat stomach pain and h pylori, while Oregano oil can help treat gastric ulcers. Lemon essential oil has shown to be effective in reducing nausea and vomiting, particularly during pregnancy.

Emotional/Mental Health
One of the most effective ways to utilize essential oils is for lowering stress levels and reducing anxiety.

Black Pepper oil can also be used in the fight against diabetes and hypertension, potentially even preventing them. Lemon Balm, also known as Melissa, is perhaps the most potent oil for heart health. It can help to regulate glucose levels in patients with diabetes, lower triglycerides, and help control of elevated cholesterol levels. Lemon balm may also aid in the treatment of hypoglycemia when administered at low concentration.

On the other end of the heart health spectrum, Lime may be used for metabolic disorders because it may benefit people suffering from dyslipidemia and hyperglycemia.

Infections and Viruses
It has been found that essential oils can be an effective alternative to antibiotics and potentially used to combat drug-resistant superbugs. In fact, four essential oils, Cinnamon, Oregano, Immupower and Purification all showed superior responses to both Penicillin and Ampicillin in their ability to kill the microorganisms. The antimicrobial properties in Lemongrass oil can be an effective solution for treating antibiotic resistant staph infections. Rosemary oil can also aid in fighting off drug resistant infections, while Oregano has been shown to be effective in battling the norovirus.

Lavender oil could be used to combat common skin and nail infections, and a study on Lemon Myrtle found that it can treat molluscum.

Inflammation
Researchers have found that six essential oils, including Thyme, Clove, Rose, Eucalyptus, Fennel, and Bergamot, can each inhibit the inflammatory COX-2 enzyme, working in a manner similar to resveratrol, the chemical linked to the health benefits of red wine.

Basil essential oil has the ability to prevent salmonella in food. Lemongrass can inactivate salmonella on leafy greens. Tarragon essential oil has antibacterial properties, particularly shown on two important pathogen bacteria (S. aureus and E. coli) and can be applied as a preservative in foods such as cheese.

Lavender oil is especially useful on the skin, and Melaleuca, also known as Tea Tree oil, can reduce histamine-induced skin irritations and inflammation. Copaiba has shown to be effective in fighting acne, due to its anti-inflammatory, healing, and antiseptic properties. And a recent article in Forbes even noted that essential oils are being used at barber spas and in luxury shaving lines.

  1. This is an excellent article and resource. I will be bookmarking this for future reference. Thank you for putting this together.

  2. Maggie Santos Viera says:

    Great info :-)

  3. Where’s the research? Statistics? This is still showing that there is no scientific evidence to these oils. Simply stating that a study found oils to be useful isn’t sufficient. How many participants, variables, etc? In the end this is just pseudo science.

    • Thanks for your inquiry. Any of the live links in the post will get you to the research, where you can find the scientific data, participants, variables, etc. for each of the claims in the post.

  4. Confused….if you click on the names of the oils she has linked them to a study supporting her claims…check it out!

  5. I’m disappointed as the 3 articles I have now clicked on are poorly conducted science with methods and conclusions that do not show support of alleviating the ailment. They DO seem to show a very small increase with antioxidants being very slightly higher which is good. I have been looking into oils for some things but they may not be helpful for what I’m looking for. Thanks for sharing these peer reviewed articles. They have been very helpful.

  6. Is there anything for autism?

    • Log Cabin Mamma says:

      Diana,
      I have a friend who is an RN and has a son who was diagnosed with regressive autism shortly after an immunization at age 4. Up to age 4 her son was a normal communicative demonstrative little boy . After, he became completely withdrawn and uncommunicative. He continued to regress rapidly until at around age 14-15 she discovered YL Essential Oils. After approximately one yr. on a YL oil protocol he is completely verbal and becoming more and more demonstrative. He knows and ask for the oils he needs to do life. She says after 12 yrs. she is finally getting her son back.

  7. Yes, there are several things for autism. Go young living website. You want to reduce stress with Bergamont, geranium, and clary sage. Just a few drops in palm of hand and massage in. Stimulate senses, Basil, lemon, peppermint, and Rosemary. I am sure there are more you can use for other symptoms.

  8. Real scientist says:

    The first reference I checked was for the valerian OIL. However, the research cited was for a study which tested valerian in PILL form – 800 mg. You cannot generalize from one form of a chemical to another. This is an example of bad thinking.

  9. Do you have this (and part 2) as a PDF? I would love to be able to save it in my kindle and reference it when I don’t have an internet connection!

  10. Thank you <3

  11. what oil is best for tennitus?

  12. I think that if you are planning to show the studies and research, a quick statement at the top of the article would be great to show that they are linked in the article. If someone is quickly perusing this, they would think there is no research cited. Frankly, if I had not glanced at the comments, I would have dismissed this article because I didn’t see any. I will now read it and if it seems well done, I will share with my essential oil distributors.
